' COMBINED STOP LUG AND CENTER FILLER CASTING.

Application filed september 22, 1926. Serial No. 136,946.

This invention relates to combined stop lug and center filler castings.

An object of the invent-ion is to provide a combined back stop and center casting which has striking faces adapted to co-operate with a draft gear having thehusual yoke, and whiclrcasting has an integral per 'lorated center pin section, together with a transverse front wall against which the striking faces ofthe casting are braced, transverse diaphragms connecting the bottom and side walls and. center pin section of the casting, and a longitudinally extend.- ing diaphragm which connects the front and rear walls of the casting, intersects certain of the transverse diaphragms, and is connected to the center pin section, providing a simple construction of great strength and compactness o Other and further objects of the invention will more clearly appear from the description and claims hereinafter following. In the drawings, forming part of this specification, Figure 1 is a top plan View of a combined stop and center casting constructed in accordance with my invention, and showing the same applied to the center sill plates of a railway car, portionsof the usual shock absorbing mechanism being shown in dotted lines. Figure 2 is a central vertical longitudinal sectional view through the center casting, and showing said casting detached from the center sill plates. Figure 3 is a transverse vertical sectional view taken substantially on the line 3-3 of Figure 1. And Figure 4 is a. transversevertical sectional vlew of the mvention corresponding substantially to the line 44 of Figure 2.

As shown in the drawing, the numerals 5-5 represent spaced center sill plates of Y usual construction having angle members 6-6 secured to the lower outer edges there of, and having oppositely arranged angle members 7-7 disposed along the innerlower edges of the center sill plates 5-5. V I

The combined back stop and center filler casting is adapted to be arranged between the center sill plates 5 5 as shown, and said casting includes side walls 8-8 which are oif-set at the lower portions as indicated at 9 to accommodate the verticalflanges of the angle bars 7-7 secured to the innerlower faces of the center sill plates- The casting also includes a bottom wall 19 which sen:

nects the side walls 8-8 and rests upon the horizontally extending flanges of the angle member 7-7. The bottom wall 10 is cut out at its forward portion as indicated at 11 to provide clearance for the end of the draft yoke shown in dotted lines in Figure- 1, the portion of the bottom wall at each side of the cut-out being integrally connected with the oppositely extending inturned flanges 12-12 formed upon the forward ends of the side walls 8-8, said flanges beingarranged to provide stops for the rear end of the shock absorbing mechanism as shown in dotted lines in Figure 1. I i i e The flanges 12-12 are braced by means of a top rib 13 which extends from each ofthe flanges in an inclined direction toward the adjacent side wall. ribs indicated at 14 are provided which extend from each flange 12 inwardly where they merge into a forward transversely extending diaphragm or" wall 15, said wall being formed integrally with the bottom wall 10 of the casting a slight distance in the rear of the cut out portion 11 and having its ends connected to the side walls.

At the opposite end of the casting there is provided a rear wall or diaphragm 16 of somewhat restricted height whichconnects the side walls 8-8, and bottom wall 10 of the casting, as best shown in Figure 2, portions 17-17 of the side walls 8-8 at the rear of the casting extending somewhat beyond the diaphragm or end wall 16, the portions 17, as well as the remaining portions of the side walls 8-8 being provided with a plurality of rivet holes indicated at 18, adapted for the reception of rivets 19, Which-are utilized for securing the casting in position between the center plates.

Intermediate the front'and rear walls ordiaphragms and '16 is provided an inter mediate transverse diaphragm 20 formed integrally with the side walls 8-8, the top edge portions of the diaphragm being inclined toward the bottom wall 10, and at the center the diaphragm 20 is formed integrally with an annular centerpin section 21 in which is formed the king pinopen'ing 22, the open 22 extending downwardly through the bottom wall 10 as best shown in Figures 2 and t the bottom wall at a point adjacent the center pin section being depressed as indieated at At opposite sides of the central king pin section are diseased trans Additional bracing versely extending diaphragms 24 and 2 which connect the side walls 8-8ot the casting and the bottom 10 thereof, said diaphragms being spaced longitudinally of the casting irom the diaphragm a suitable distance as shown, said diaphragins each having its top edges inclined toward the center in the direction of the bottom wall 10 longitudinally extending centrally disposed diaphragm is provided which is connected at its forward port-ion with the wall 15 and at this point is ot a height cor responding thereto, the diaphragm 26 er;- tending :rearwardly and gradually diminishing in height, until the sane intersects the diaphragm 9A and thence merges into the annular wall forming the center section 531. The diaphragm 26 is interrupted by the center in section but on the o3 osite side of said section is connected integrally therewith as shown at 27 and thence intersects the diaphragm o and merges with the end wall 16, theh'ei-ght of the diaphragm gradually diminishing to correspond to the height of the diaphragm and end wall 16 at their central portions.

By reference to the preceding description taken in connection with the'drawings, the purpose and use of the casting will be clearly understood, the braced flanges at the forward portions of the casting providing abutments for the rear of the shock absorbing mechanism, while the cut out portion 11 permit-s the necessary movement of the yoke. The center pin section is adapted for thereception of the usual center pin, and by the use of the transversely arranged diaphragms connecting the bottom wall, side walls and '1. A combined center filler andfstop lug casting comprising longitudinally arranged spaced side walls adapted to be secured to the jCfillftQ-l sijlls of a railway car, an 111t6- grally transversely extending horizontal bottom wall having a central cut-out" section at its -forward portion to permit movement 0'! said castin nee le? adraft yoke, transversely extending integral walls at the forward and rear portions of said front wall being disposed in the rear of said cut-outsectionand formeiil integrally with saidside and bottom wall, and the rear wall merging with said side and bot-torn walls, a center pin section, iormed integrally with said bottom wall and a transversely extending diaphragm connecting said central section with said side walls, a (ll2t1')l11&gll1 at each side of said center section, said diaphragms connecting said side walls and said bottom wall, a longitudinally extending centrally dispose-d liaphragm connected with said front and rear wall and with said center pin section, and intersect-- in g the remaining diaphragnis, being formed integrally therewith, and inturned flanges atthe forward portions oi said sidewalls-to provide stop lugs, said "flanges being braced by means of horizontally disposed ribs extending betweensaid flanges and the forward wall of said casting.

2. A combined center'filler and sto ing, comprising side walls, a bottom, and sp ced"endwalls connecting said sides and bottom; spaced stop members braced against said side walls and the adjacent end wall; a plurality of transversely extending diaphragms intermediate said end walls and connecting the side walls and bottom wall or said filler, a center pin section'connected to 7 said bottom wall and connected to said side walls by one of said transverse diaphragins, and centrally disposed longitudinally extending means connecting said end walls with said center section,.and intersecting the remaining diaphragms.

3. A combined. center filler and stop casting, comprising side walls, ;a bottom, and spaced end walls connecting said sides and bottom; spaced stop members braced against said side walls andthe adjacent end wall; a plurality of transversely extending'd' phragms intermediate said end wa ls and connecting-the side walls and bottom wall of aid filler, a center pin section connected to said bottom wall andconnected to said side walls by one of said transverse diaphragms, and centrally disposed longitudinally extending means connecting :said end walls with said. center section, and intersecting the remaining diaphragins, said center pi section being depressed with reference to the side and an end wall, and said diaphragms being inclined toward said center section.

In witness that I claim the fort going I have hereunto subscribed my name this 15th day of September, 1926.
